The Property is located at the northern extent of the southern Peru Au-Ag epithermal belt. Mineralisation identified at the Property is of a high-sulphidation (HS) epithermal type hosted in volcanic rocks close to the Chonta fault, a regionally significant NNW trending structure. The Chonta fault is a major geological break which separates Cenozoic volcanic deposits from folded Paleozoic sediments. Zoned alteration and mineralisation are centred on dacitic and rhyodacitic domes intruded close to the Chonta Fault at its intersection with subordinate NE faults. Outcrop is obscured by vegetation and quaternary deposits. The north-northwest trending Chonta fault, obscured in part by quaternary deposits, separates folded Cretaceous and Jurassic sediments from Cenozoic volcanics and is the main conduit for extensive hydrothermal alteration. Hydrothermal alteration related to inferred buried intrusions is recorded to the southwest of the Chonta fault in Cenozoic volcanics. Centres of alteration, observable on remote sensingimagery, are mapped along the Chonta fault. Alteration is particularly strong where secondary northeast faults intersect the Chonta fault. Variably sub-cropping and outcropping dacite and rhyodacite domes and more recent volcanic deposits dominate geology and the Property. Domes broadly define the margins of a collapsed caldera structure measuring 4.5 by 3.5 km, elongate along a north-northwest trend (Coffey, 2010). The NNW Andean trend is well developed a ........

Gold mineralization at Corihuarmi is mined by open pit methods. In 2020, the average grade produced was 0.25 grams per tonne (“g/t”) gold, with 22,593 ounces of gold recovered through a leaching process.

Mining at Corihuarmi uses a conventional truck and excavator configuration. Open pits are mined on 5 meterhigh benches through drilling, blasting, loading and hauling unit operations. The material transportation circuit is performed in two parts. First is from the pit to the crusher, and the second one from the crusher to the leach pad. If the mineralized material does not warrant crushing, the material is transported directly to the leach pad as run-of-mine. The waste is transported to the waste dump.
